he'd be great in the Arsenal midfield. his form is a bit down right now, so it might be a good time to test CSKA Moscow's resolve to keep Keisuke. It'd be one of the best signings we could make, plenty of creativity, solid work rate, and ranks up there as a big name signing we're all clamoring for. The pecking order would probably put him behind Fabregas and Nasri, and just in front of Ramsey. Can probably play out wide as well, and provides us another option when RvP's radar is off (it's getting worse for Robin!)
It doesn't really address our main issues yet, though.
